To start our discussions on the principles, we will refer to two definitions from of the terms from a medical dictionary ([Stedl995]), which we take representatively from the immense number of definitions that can be found in the literature: ''be-hav-ior: 1. The actions or reactions of persons or things in response to external or internal stimuli, 2. The manner in which one behaves, " and Chapter 3 36 ''phys-i-ol-o-gy: 1. The biological study of the functions of living organisms and their parts.

For evaluations in the context of this book, we focus our views on user authentication by verification, thus determination of BER and PC becomes obsolete. 28 Chapter 2 It is necessary to mention that in a wide number of publications, accuracy measures are referred to as False Acceptance Rates (FAR) and False Rejection Rates (FRR). In contrast to the FMR and FNMR measures, which are determined based on discrete decisions of the comparison of features of each actual test sample with exactly one biometric template, FAR and FRR rates are determined at a more abstract level of the authentication process.

Physical removal of organic material from human bodies for biological analysis. g. samples of hair or dander) undergo Deoxyribonucleic Acid (DNA) analysis. DNA carries the genetic instructions for the biological development of cell forms, as well as for many viruses. Today's DNA analysis is based on a model introduced by Watson and Crick [WaCrl953], where the genetic instruction are coded as sequences of building blocks called bases. By comparing order and length of two or more of such sequences, based on different samples, it is possible to authenticate persons.
